PTFE-Solid™ Self-Lubricating Copper Sleeve

Definition

Self-lubricating inlay water-lubricated copper sleeves are a type of sliding bearing material that integrates self-lubrication and water-lubrication technologies, aiming to provide excellent lubrication effects and wear resistance. Here is a detailed analysis of this copper sleeve: Structural characteristics: The self-lubricating inlay water-lubricated copper sleeve is composed of a copper base and solid lubricants embedded within it. These lubricants can be substances such as PTFE (polytetrafluoroethylene) in the form of particles or fibers. Additionally, the interior of the copper sleeve is designed with water channels or water cavities for the circulation of water or other liquid lubricants, which further reduces friction and wear.

Structural Principle

This product is made of high-strength tin bronze base material, with high-purity PTFE (white graphite) embedded as a solid lubricant, achieving oil-free self-lubrication. Compared to traditional black graphite, white graphite does not flake off, is pollution-free, has high temperature resistance (up to 400℃), and possesses excellent electrical insulation properties. It is suitable for clean workshops, food and pharmaceutical industries, semiconductor equipment, etc., where high cleanliness requirements for lubrication are necessary. The maintenance-free design significantly reduces the operating and maintenance costs of the equipment.

✨Key Advantages

Why choose us?

Q1: What are the differences between the white graphite copper sleeve and the ordinary graphite copper sleeve?
A: The traditional black graphite is prone to falling off and causing pollution. Our white graphite does not fall off, does not produce dust, is resistant to high temperatures (400°C), and is electrically insulating. It is suitable for clean environments such as semiconductor, food and pharmaceutical industries.
Q2: Can it really be completely without lubrication?
A: Yes. The solid lubricant embedding technology enables lifelong maintenance-free operation. There is no need for external lubricating grease, which saves operation and maintenance costs and eliminates oil pollution.
Q3: What is the working temperature range?
A: -200°C ~ +400°C (instantaneous 450°C), which is much higher than that of ordinary self-lubricating bearings. It is suitable for extremely cold and high-temperature baking equipment.
Q4: Can non-standard customization be supported?
A: Full-size non-standard customization is supported. New customers can apply for two free samples.
Q5: Which industries are applicable?
A: Semiconductor, food and pharmaceutical, aerospace and military, new energy, medical equipment, etc., which have requirements for cleanliness or high-temperature resistance.
